Bitcoin Mining Giant Bitmain Unveils ‘Next-Generation’ 7nm ChipBitmain, the world’s most valuable cryptocurrency company, isn’t ready to relinquish its position as the dominant manufacturer of bitcoin mining chips — at least not yet.
The China-based firm on Friday announced that it had developed a new 7nm application-specific integrated circuit (ASIC) mining chip for the SHA256 algorithm used by bitcoin, bitcoin cash, and many other cryptocurrencies.
Bitmain CEO Jihan Wu announced the new chip — the BM1391 — at the World Digital Mining Summit in Georgia, adding that it will be deployed in the firm’s next generation of mining rigs, the follow-up to the Antminer S9.
GMO Internet, a Japanese tech company based out of Tokyo, unveiled a 7nm chip in June. According to Wu, the BM1391 has an energy consumption ratio of 42W/TH, while GMO’s B2/B3 miners consume 81W/TH at peak.
Notably, Bitmain’s announcement came just two days after competitor Bitfury unveiled a new SHA256 ASIC chip. The “Bitfury Clarke,” while much larger than the BM1391 at 14nm, offers “unparalleled efficiency,” according to the company. Per the company, each chip can achieve a hashrate of 120GH/s with a power efficiency of 55mW/GH. Bitfury, incidentally, operates a mining farm in Georgia, where Wu announced Bitmain’s new chip.
